This is weird for ya’ll, but honestly Imma just tryna do what someone in Pinterest suggested and create a blogpost where I should post what I learned for the day. So this is what I learned on my Biomolecules subject today #BSBiologyStudent
So biological molecules is a field of study that has both chemistry and biology in use. It studies the chemical reactions within living organisms such as plants and animals. Apparently, viruses aren’t living organisms because according to this one university in Arizona, scientist don’t believe they are, because viruses, despite having their own complex structure of nucleic acid and proteins, is not active until they become attached to a host cell, per se, human cells, that’s when they start to activate and multiply through the help of that cell. Since it needs a living cell to be alive, and does not use its own energy, viruses are living.
Biomolecules has four major types, carbohydrates which if ingested turns into energy instantaneously, lipid which is a fat that has a hydrophobic tail, it hates water and repels it, lipids is what protects the cell from materials outside of the cell, combined with protein which is made of amino acids, and then we’ve got nucleic acids, which composes our DNA.
To test for carbohydrates in our food, we can use either the Iodine test or the Molisch test, the iodine test only needs an iodine solution and a food sample, while the Molisch test, you need Molisch reagent and Concentrated H2SO4 or Concentrated Sulfuric acid. The iodine test works this way; the solution is light brown in color, and once mixed with starch or any food that has starch such as rice, pasta, corn or wheat, then the solution will give a positive result by turning a blue black color. The Molisch test on the other hand is not so easy, and you need to have some safety PPE’s, such as gloves and safety goggles. This test works by mixing your chosen substance to study, say maltose solution and glycine, mix this with 2ml of Molisch reagent and concentrated sulfuric acid. A positive result will show a purple ring on the interface of the solutions, while the a negative result will show a green ring on the interface, in this case since we’re determining which has carbohydrates, the one solution with maltose showed a positive result seeing as maltose is carbohydrates, it is a double sugar or a combination of two glucose molecules.
The Buiret test on the other hand test for proteins or a peptide with two or more amino acids. To do the test you have your chosen samples to study, in this case, glucose, glycine and gelatin. In this study, the gelatin garnered a positive result after mixing it with copper sulfate and 2 normal sodium hydroxide, which gave a purple colored solution, indicating a positive result of protein on the said solution.
The last test is the Sudan IV Test, Sudan IV is a dye that indicates the presence of fat in a solution, in the experiment done, distilled water is put inside two test tubes and vegetable oil was added in one of those test tubes. After placing these on the test tubes, the researcher proceeded to add the dye into both the tubes in equal amount. After properly mixing the solutions, it is noticeable that one of the solution has a brighter magenta color on its top, where the vegetable oil was mixed/floating in. Sudan IV dye is a fat-loving solution and its no wonder it was attracted to the oil almost immediately. It yeilded a positive result as the dye attached itself to the fat. Other test can be done to test for fat, but I’m not discussing it anymore because it wasn’t discussed to me either.
If I said something wrong here science side of tumblr, feel free to give me notes or to add on to the bullshit I’m saying, because I’m pretty sure it’s going to help me in some way in retaining this information more. Enjoy my blabbering.
